Originally posted by ctrout I have seen a K1000 SE with black leatherette and I would assume that the K1000 SE was also available with brown leatherette although I can't remember if I've ever seen one.
The SE came with at least three different coverings: black (similar to Spotmatic and other K-series bodies), brown, and black diamond pattern (rubberized?). A Google image search should bring up examples of all three. The brown versions are fairly common; at least those I have seen have all been brown. I am not sure, but I believe the black and brown are leather, not leatherette. Note too, that there are both engraved and "sticker" versions of the K1000 SE. Your brown camera may well be a "sticker" SE that has lost its sticker. Does it have a split-image/microprism focus aid?
As for desirability and value for collectors...both, like beauty, are in the eye of the beholder. No version of the K1000 is particularly rare, except perhaps the diamond leatherette SE.
